Sawdust machine is designed and developed according to industrial requirement. It belongs to wood crushing and pulverizing equipment. It has a reasonable design and stable structure. It is a safe, endurable, efficient sawdust making machine. Besides, it is highly eco-friendly and saves energy in order to reduce the production cost. Wood grinder machine uses blade cutting and high speed airflow crushing to reduce the wood into sawdust. While the blades inside are cutting with a high rotating speed, the rotor generates strong airflow which rotates at the same direction as rotor. As the blades rotate and cut, the airflow crushes the material at the same time. That way, the sawdust making efficiency can be increased greatly. Xzcfsd
